13 Claims.

' My invention relates more particularly to building siding material of .sheet or panel-like form made to simulate -the appearance of shingles, as for example and more particularly,

, to provide a siding material panel of such con- 15 struction that when a number of such panels are grouped together the structure will present the appearance'of a shingle structure wherein certain of the shingles extend at their lower edges below the shingles next laterally adjacent thereto; and other objects as will be manifest from the following description.

Referring to the accompanying drawing: I

Figure 1 is a face view of a grouping of similar building siding panels embodying my invention, the two upper panels being shown partly broken away and vertically spaced from the panel beneath them, shown in full, to better illustrate a certain feature of the invention.

Figure 2 is a plan or top edge view of thepanel; Y

Figure 3, an enlargedsectional view taken at the line 3 on Fig. 1 and viewed in the direction of the arrow; and v Figure 4 is a detail face view of the top edge 35 of the lower panel of Figure 1, showing its appearance separate from the upper panels of said figure.

I have illustrated my invention as embodied in a building siding panel which in practice would be provided of a number sumcient when grouped together to cover the portion of' the building to ,be surfaced.

In the case of the particular panel shown-it is formed of a base or board portion 4 of any suitable material, as for example insulation board. such as is commonly used, impregnated with waterproofing material in accordance with common practice.

Over the entire outer surface of the panel is a coating of adhesive, such as for example asphalt, covered by a layer of grit represented at 5, pressed into the coating and adhering thereto over its entire surface. The grit 5 is further locally pressed into the coating (the coating being hot), to become covered thereby, along lines or stripes delineating the particular shingle design which the panel is to display. In the particular panel shown the shingle simulating portions represented at 6 are provided in twohorizontal rows, the shingle-simulating portions being of different widths and shown as simulatin wood shingles. The shingle-simulating portions" of the rows thereof are staggered relative to each other and the lower ends of alternate shinglesimulating portions of each row extend below the lower edges of the shingle-simulating portions next laterally adjacent thereto.

The stripe of asphalt coating exposed between the rows of shingle-simulating'portions and extending lengthwise of the panel and of zigzag form as shown in Fig. 1, is represented at I and the vertical stripes of the asphalt coating which separate the shingle portions of each row are represented at 8. The stripe I is of zigzag form to cause those portions of the stripe whichrextend below the shingle-simulating portions of the upper. row thereof the lower edges of which are below the laterally adjacent shingle-simulating portions, to be of substantially the same width as the portions of the stripe below the other shingle-simulating portions of this row.

It is contemplated that, in covering a wall surface a plurality of the panels shown be assembled together in matching relation to produce a continuous uniform design, the panels of alternate horizontal rows thereof being staggered relative to the panels of the rows immediately above and below them, as indicated of the upper panels in .Fig. 1, wherein the two upper panels, portions of which are broken away, are shown as meeting midway between the ends of the panel beneath them as indicated at 9. As the lower edges of certain of the shinglesimulating portions 8 at the lower edge of the panel, when the panel is grouped, with similar panels, as shown, register with shingle-simulating portions of panels beneath it, the upper edges of which portions extend flush with the upper edge of the exposed surface of the lower panels, the panel is formed to provide stripes ill of asphalt coating, depressed relative to the exposed surface of the panel, along the lower edges of the first above referred to shingle-simulating portions. Furthermore, the upper edge portion of the panel is formed with stripes l I, likewise depressed, of asphalt coating which, when this panel is grouped with similar panels as shown,

, will be in registration with such of those of the shingle-simulating portions of the panels immediately above it as extend to the extreme lowthan the ground, a person viewing the wall and looking upwardly at it, views it at a decided angle to the horizontal and therefore in perspective. As the horizontal stripes of asphaltcoating between theshingle-simulating portions of each panel and between adjacent panels (these stripes presenting the optical illusion of thick butt shingles), are inset from the exposed surface of the panel, forming depressions, such depressions if of straight sided form would present to the eye of the observer viewing the siding on the wall of a building, at an angle as stated, decidedly narrower stripe eifects as compared with the relatively wide stripe effects presented to the eye of the observer viewing the surfacing-substantially horizontally. Thus the optical illusion of thicker butt shingles produced by these horizontal stripes becomes successively diminished toward the top of the surfaced area producing an appearance decidedly' non-uniform and therefore objectionable.

To minimize this objection the lower side wall of the horizontal stripe-forming zigzag depression 1 throughout its length and the lower side walls of the stripe-forming depressions H are" sloped downwardly and outwardly throughout their length as represented at [2 of the central stripe-forzning depression I and at I3 of one of the stripe-forming depressions extending along the top edge of the panel.

- While I have illustrated and described a particular construction embodying my invention, I do not wish to be understood as intending to limit it thereto as the same may be variously modified and altered and the invention embodied in other forms of structure without departing from the spirit thereof.

What I claim as new and desire to secure by letters Patent is:

j 1. Building siding material comprising a base member presenting shingle-simulating portions spaced from each other, the surface of the ma- Y terial between said shingle-simulating portions being darker than said portions, said surface below certain of said shingle-simulating portions being depressed, the lower side walls of said depressions inclining outwardly and downwardly from the bases of said depressions to an overall width of-depression substantially equal to the width of said darkened portions.

2. Building siding material comprising a base member presenting shingle-simulating portions spaced from each other, the surface of the material between said shingle-simulating portions being darker than said portions, said surface below said shingle-simulating portions being de-- pressed, the lower side walls of certain of saiddepressions inclining outwardly and downwardly from the bases of said depressions to an overall width of depression substantially equal to the in i s exposed surfacev delineating shingle-simulating portions, the surfaces of said depressions being darker than said portions, the lower side walls of said depressions beneath certain of said portions inclining .outwardly and downwardly from the bases of said depressions to an overall width of depression substantially equal to the width of said darkened portions.

4. Building siding material comprising a. base member presenting substantially horizontally disposed rows of shingle-simulating portions spaced from each other, the surface of the material between said shingle-simulating material being darker than said portions, said surface below certain of said shingle-simulating portions being depressed, the lower side walls of said depressions inclining outwardly and downwardly from the bases of saiddepressions to an overall width of depression substantially equal to the width of said darkened portions. 5. Building siding material comprising. a base member presenting substantially horizontally disposed rows of shingle-simulating portions spaced from each other, the surface of the material between said shingle-simulating material being darker than said portions, said surface below said shingle-simulating portions being depressed in zigzag relation in alternate depressions, the lower side walls of certain of. said depressions inclining outwardly and downwardly from the bases of said depressions.
